Summary
This Nature Geoscience study presents a modelling assessment of enhanced rock weathering (ERW) as a negative emissions technology applicable to UK agricultural land. As suggested by the title, the authors quantified substantial carbon sequestration potential from spreading finely ground silicate minerals on farmland, integrating soil chemistry, crop productivity, and climate data across UK regions. The work suggests ERW could offer a significant yet technically and economically constrained pathway for climate mitigation whilst potentially improving soil health and crop yields.
UK applicability
The findings are directly applicable to UK farming policy and land management, as the study was conducted at national scale using UK-specific soil, climate, and agricultural data. Results could inform future agricultural carbon schemes and land-use strategy, though scalability and farmer adoption remain practical barriers.
Key measures
Carbon dioxide removal potential (tonnes CO₂ per hectare per year); spatial applicability across UK soil and climate zones; economic feasibility; agricultural co-benefits
Outcomes reported
The study assessed the potential for enhanced rock weathering (ERW) — spreading crushed silicate minerals on agricultural land — to sequester atmospheric carbon dioxide in the United Kingdom. It modelled carbon drawdown rates, scalability, and co-benefits across different soil and farming contexts.
